Abstract (en)

[origin: WO0190018A1] The invention relates to a device for atomizing and comminuting liquid melts which comprises a slag tundish in which a propellant gas lance opens into the outlet. The dimensions of the device are such that: the width of the gap between the lower edge of the underflow weir and the tundish bottom is less than 20 %, preferably less than 15 %, of the inner width of the outlet; the bottom of the tundish is provided in the shape of a funnel in the area between the lower edge of the underflow weir and the outlet, and; supercritical steam for forming an under-expanded free jet is forced inside the melt jet via the propellant gas lance, whereby the velocity of flow at the nozzle opening of the lance is set to the speed of sound.
